1. (x+4)²= x²+2(x)(4)+4²=
4. (p+5q)²= p²+2(p)(5q)+5q²=
7. (5x+3y)²= 5x²+2(5x)(3y)+3y²= 
10. (6x-5y)²= 6x²-2(6x)(5y)+5y²=
2. (3x+2)²= 3x²+2(3x)(2)+2²=
5. (a+2b)²= a²+2(a)(2b)+2b²=
8.(a-3b)²= a²-2(a)(3b)+3b²=
11. (x²-5)²= x⁴-2(x²)(5)+5²=
3. (a+1)²= a²+2(a)(1)+1²=
6. (x-5)²= x²+2(x)(5)+5²=
9. (6-x)²= 6²-2(6)(x)+x²=
12. (3a²+x²)²= 3a⁴-2(3a²)(x²)+x⁴=
